As everyone has stated, it's all really up to personal tastes
In my opinion, the DC2R is more of a driver's car - more rawness, lighter, more nimble; the driver is able to experience the thrill
Opposed to DC5R - I feel it's been tamed down a tad, heavier, more of a passengers car
Don't get me wrong, both are fantastic but I'd go with the dc2r - they're cheaper as well so more mods :P
DC5R are however, are newer (still quite old) and have the k20a..
